Riven MLST resources
From A look inside The Link @ wiki
These are movie lists. The record structure is similar to PLSTs:
unsigned short | movie_id | Resource ID of the corresponding tMOV movie |
unsigned short | code | Used by script commands to reference the movie record |
unsigned short | left | Movie position within the game window (pixels) |
unsigned short | top | |
unsigned short | u0[3] | |
unsigned short | loop | 0 or 1, 1 means the movie must loop forever |
unsigned short | volume | Volume of the movie sound track (details still unknown) |
unsigned short | u1 |
As for unknown fields: u0 seems always 0000 0000 ffff and u1 seems always 1. Changing them produces no observable effects.
